Scavenging is a process of pushing out exhausted gas charge from the cylinder and allowing fresh air to enter in to the cylinder for the next cycle. Combustion process takes place inside the chamber in cylinder. This process is generates power and for combustion fresh oxygen is needed. As oxygen content is directly proportional to efficient combustion and hence power generation therefore scavenging is important in IC engines.
